The first step was a study of the factors that effect thin film circuit density. The study resulted in a list of rules for microcircuit resistor network design that were used to design a differential amplifier circuit that demonstrates the degree of circuit complexity that can be achieved on a 0.310 x 0.310 inch square wafer. This phase of the development program concluded with the fabrication of fifty differential amplifier circuits that were electrically tested and analyzed to verify the results of the circuit design study. The second step was the fabrication of 2000 resistor boards. A cost analysis of the production run demonstrated that the per resistor cost on the 0.310 x 0.310 wafer can be as low as 3.75 cents per resistor. The third step was the development of two types of thin film capacitors - one containing a silicon monoxide dielectric, the second containing a photoresist dielectric. The two capacitor types were manufactured in a limited quantity 100 units. The cost per capacitor of 22 cents has been set for the 0.310 inch wafer size. A life test program was run on 50 resistor networks and 50 capacitor networks to demonstrate the load life capability. Author
